GENERAL DESCRIPTION

The MSM9006-01 is an LCD driver for a 1/3 duty dynamic display. It can directly drive an LCD
with a maximum of 123 segments.

• DATA I/O

This is a serial data input/output. The pin is in output state for the duration from the first shift
clock rising after "Key Data Output" command is entered, to the load signal rising, and in input
state otherwise. (The pin is in input state after reset.)
The relationship between data level and operation is shown below.

• CLOCK

This is an input pin for the shift clock. DATA I/O pin data is either input or output in
synchronization with the rising of the clock.

• LOAD

This is a load signal input pin. It is used for transferring serial input data to a latch for display,
entering commands, or resetting the output state of the DATA I/O pin.

MSM9006-01, -02¡ Semiconductor

• R0 - R4

These are keyswitch scan signal output pins. During the scan operation, "L" level is output in
the order of R0, R1, …, R4. All signals go to "L" level when scanning stops. (See keyscan)

• C0 - C4

These are input pins that detect the key status. Pull-up resistor is included. Key matrices are
formed with R0 -␣ R4 pins.

C0 C1 C2 C3 C4 R0 R1 R2 R3 R4

• INT

This is the keyscan end signal output pin. This pin goes to "H" level when one scan cycle ends,
and returns to "L" level by a load signal after data is output or after the "Keyscan Stop" command
is entered. (This pin also returns to "L" level at reset.)

10/18

MSM9006-01, -02¡ Semiconductor

• RESET

This is the reset signal input pin that initializes the device, and it is activated at "L" level. Pull­up resistor is included. The power-on reset operation is performed by externally connecting a
capacitor. (See "Power-on Reset" in REFERENCE DATA)

• SEG1 - SEG35

These are output pins for the LCD display, and are connected to the segment pins of the LCD
panel. See the section on data configuration for the correspondence between SEG output and
input data.

• COM1 - COM4

These are output pins for the LCD display, and are connected to the common pins of the LCD
panel.
In the case of MSM9006-01, the COM1 to COM3 pins apply.

• SEG36/PO5 - SEG40/PO1

These pins can select the output pins for the LCD display (segment pins) or general port output
pins by setting with commands.

• SEG 41/LED

This is an output pin for the LCD display (segment), or LED drive selection with command. If
LED drive is selected, the LED and current limit resistor are externally connected.

Display Data Input

As shown in the section on data configuration, the data for display consists of data field
corresponding to segments ON/OFF and of command field indicating display data input.

Set the C0 and C1 bits of the command field according to the COM pins corresponding to the
display data. LED display data when LED display pin is selected and output port data when
output port pin is selected correspond to common 1. Data input to the DATA I/O pin is
caputured by a shift register at the rising edge of a clock signal, then it is transferred to a data
latch for display when the LOAD signal is at "H" level, and is then output through a segment
driver.

Key Data Output

The status of a key switch is indicated by ON = 1, OFF = 0, and is read as 25-bit serial data. (For
information on the sequence, see the section on data configuration.) To output data, the "Key
Data Output" command is first entered. Then data is output synchronizing with the rising edge
of a clock signal. If a LOAD pulse is then added, the DATA I/O pin returns to the input status,
and the next data or command can be input.

Keyscan

Keyscan starts when the key status is changed, or when the "Keyscan Start + key data output"
command is entered. Scan continues until the "Keyscan Stop" command is entered. (Scan is in
stop state at power-on reset.)

When 1 keyscan cycle ends, the INT signal goes to "H" level, so this signal can be used as an
interrupt flag. The INT signal is reset when the LOAD pulse is input after the key data is output,
when the "Keyscan Stop" command is entered, or when a reset signal is applied.

Notes: 1. A recognition error (that is, a switch that was not pressed is recognized as being

pressed) may occur when three or more key switches are pressed at the same time.
If simultaneous pressing of three or more key switches must be recognized, insert
diodes serially to each switch. If simultaneous pressing of three or more key switches
is required not to be recognized, a possible approach is to program so that the entire
key information will be ignored if there are three or more 1s in read data.

2. A change of key status is detected as a change of column inputs (C0 - C4). Therefore

if multiple switches which connected to the same column are pressed at the same
time, it will not be detected as a change of key status.

MSM9006-01, -02¡ Semiconductor

Display ON, Display OFF

Upon power-on reset, the display is put in off state. To turn on the display, enter the Display
ON command.

Regardless of the display data, the display goes out by entering the Display OFF command
because the Display OFF command turns off all segments and LED display and changes the
state of the output port from "H" to "L" level.

The display returns to the initial state by entering the Display ON command because the Display
ON command resets the off-state of the display.

*1 The bits C5-C0 correspond to SEG36/PO5, SEG37/PO4, SEG38/PO3, SEG39/PO2, SEG40/

The high level selects the LCD (SEG36-SEG41) output. The low level selects the output port
(PO5-PO1) and LED output (any pin combination is selectable).

Because the pin select mode is not set upon power-on reset, be sure to put the device into pin
select mode before entering the Display On command.

Notes for Mounting the Surface Mount Type Package

The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the
